Referring to FIG. 1, the electronic device 101 in the network environment 100 may communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input device 150, a sound output device 155, a display device 160, an audio module 170, a sensor module 176, an interface 177, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one (e.g., the display device 160 or the camera module 180) of the components may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In some embodiments, some of the components may be implemented as single integrated circuitry. For example, the sensor module 176 (e.g., a fingerprint sensor, an iris sensor, or an illuminance sensor) may be implemented as embedded in the display device 160 (e.g., a display).

The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to an example embodiment, as at least part of the data processing or computation, the processor 120 may load a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134. According to an embodiment, the processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)), and an auxiliary processor 123 (e.g., a graphics processing unit (GPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operable independently from, or in conjunction with, the main processor 121. Additionally or alternatively, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be specific to a specified function. The auxiliary processor 123 may be implemented as separate from, or as part of the main processor 121.

The auxiliary processor 123 may control at least some of functions or states related to at least one component (e.g., the display device 160, the sensor module 176, or the communication module 190) among the components of the electronic device 101, instead of the main processor 121 while the main processor 121 is in an inactive (e.g., sleep) state, or together with the main processor 121 while the main processor 121 is in an active state (e.g., executing an application). According to an embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., the camera module 180 or the communication module 190) functionally related to the auxiliary processor 123.

The memory 130 may store various data used by at least one component (e.g., the processor 120 or the sensor module 176) of the electronic device 101. The various data may include, for example, software (e.g., the program 140) and input data or output data for a command related thereto. The memory 130 may include the volatile memory 132 or the non-volatile memory 134.

According to an embodiment, the receiver may be implemented as separate from, or as part of the speaker.

The display device 160 may visually provide information to the outside (e.g., a user) of the electronic device 101. The display device 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. According to an embodiment, the display device 160 may include touch circuitry adapted to detect a touch, or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of force incurred by the touch.

The audio module 170 may convert a sound into an electrical signal and vice versa. According to an embodiment, the audio module 170 may obtain the sound via the input device 150, or output the sound via the sound output device 155 or a headphone of an external electronic device (e.g., an electronic device 102) directly (e.g., wiredly) or wirelessly coupled with the electronic device 101.

The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The interface 177 may support one or more specified protocols to be used for the electronic device 101 to be coupled with the external electronic device (e.g., the electronic device 102) directly (e.g., wiredly) or wirelessly. According to an embodiment, the interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.

A connecting terminal 178 may include a connector via which the electronic device 101 may be physically connected with the external electronic device (e.g., the electronic device 102). According to an embodiment, the connecting terminal 178 may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector).

The haptic module 179 may convert an electrical signal into a mechanical stimulus (e.g., a vibration or a movement) or electrical stimulus which may be recognized by a user via his tactile sensation or kinesthetic sensation. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.

The camera module 180 may capture a still image or moving images. According to an embodiment, the camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.

The power management module 188 may manage power supplied to the electronic device 101. According to an example embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

The battery 189 may supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.

The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., PCB). According to an embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

FIG. 2A is a diagram illustrating a perspective view of the exterior of an electronic device according to various embodiments, FIG. 2B is a diagram illustrating a perspective view of the exterior of an electronic device according to various embodiments, and FIG. 2C is a diagram illustrating a perspective view of the exterior of an electronic device according to various embodiments.

Referring to FIG. 2A, 2B and FIG. 2C, the housing 210 of the electronic devices 201, 202, and 203 according to various embodiments (for example, electronic device 101) may include a first surface (for example, front surface) facing in a first direction and a second surface (for example, rear surface) facing in a second direction opposite to the first direction.

The electronic devices 201, 202, and 203 according to various embodiments may include a first display 261 exposed (or viewable) through substantially the entire area of the first surface. The electronic devices 201, 202, and 203 according to various embodiments may use all (or almost all (for example, 95% or more)) of the first surface as a display area because various elements (electronic components) (for example, receiver 255 and various sensors (for example, proximity sensor and luminance sensor)) conventionally disposed on the first surface are removed from the first surface. For example, various embodiments may use substantially all of the first surface as a display area without modifying the display as in the case of a notch design. The electronic devices 201, 202, and 203 according to various embodiments may include a first luminance sensor 211 on the upper end of the first surface. The first luminance sensor 211 normally has a very small size, and thus may not require form modification of the first display 261 as in the case of a notch design. In some embodiments, the first luminance sensor 211 may be disposed below the first display 261.

The electronic devices 201, 202, and 203 according to various embodiments may include various elements removed from the first surface, and second displays 262 a, 262 b, and 262 c, on the second surface. The second displays 262 a, 262 b, and 262 c may be exposed or viewable through a partial area of the second surface, and the various elements may be exposed through another area of the second surface.

The form (shape and size) of the second displays 262 a, 262 b, and 262 c and the various elements included on the second surface may be diversified. For example, the first electronic device 201 may have, as illustrated in FIG. 2A, a receiver 255 and a second luminance sensor 212 disposed in the transverse direction on the upper end of the second surface, may have a camera module 280 disposed below the receiver 255, may have a flash 281 disposed on the lower end of the camera module 280, and may have a second display 262 a disposed on the lower end of the flash 281 and elongated in the longitudinal direction (rectangular shape).

As another example, with reference to FIG. 2B, the second electronic device 202 may have a receiver 255 and a second luminance sensor 212 disposed in the transverse direction on the upper end of the second surface, may have a second display 262 b disposed on the lower end of the receiver 255, and may have two (or three or more) camera modules 280 and a flash 281 disposed in the longitudinal direction next to the second display 262 b.

As another example, the third electronic device 203 may have a receiver 255 and a second luminance sensor 212 disposed in the transverse direction on the upper end of the second surface, may have a camera module 280, a flash 281, and a fingerprint sensor 276 disposed in the transverse direction on the lower end of the receiver 255 and the second luminance sensor 212, and may have a second display 262 c disposed on the lower end of the camera module 280, the flash 281, and the fingerprint sensor 276.

The user of the electronic devices 201, 202, and 203 according to various embodiments may make a voice call using the second surface on which the receiver 255 is disposed. In addition, the electronic devices 201, 202, and 203 according to various embodiments may have no separate camera module mounted on the first surface, and may enable the user to make a video call or to take selfies using the camera module 280 and the second displays 262 a, 262 b, and 262 c disposed on the second surface.

The electronic devices 201, 202, and 203 may further include an antenna for short-distance wireless communication (for example, and without limitation, near-field communication (NFC), magnetic secure transmission (MST)), or a wireless charging antenna on the second or first surface.

Although the electronic devices 201, 202, and 203 illustrated in FIG. 2A, 2B and FIG. 2C have a first luminance sensor 211 disposed on the first surface, the first luminance sensor 211 may be omitted to further increase the size of the first display 261, or may be disposed on another area (for example, upper-end side surface) of the housing 210 of the electronic devices 201, 202, and 203.

FIG. 3A is a sectional view illustrating an example method for mounting a short-distance wireless communication antenna of an electronic device according to an embodiment.

Referring to FIG. 3A, the electronic device according to an embodiment (for example, electronic device 101 or electronic devices 201, 202, and 203) may include a housing 310, a first display 361, a first protective window 31, a bracket 32, a support 33, a first printed circuit board 34 a, a second printed circuit board 34 b, a flexible printed circuit board 34 c, a short-distance wireless communication antenna 397, a battery 389, a second display 362, and a second protective window 35.

The housing 310 may include a first surface and a second surface. The first display 361 may be exposed or viewable through the first surface of the housing 310. The first display 361 may include a heat-radiating sheet (not illustrated) for the purpose of diffusing heat inside the electronic device so as to lower the temperature therein or preventing and/or reducing the display panel 361 a from a backlight bleeding, and/or various display sheets 361 b for the purpose of blocking electromagnetic interference (EMI). The display sheets 361 b may, for example, and without limitation, comprise a metal (for example, copper), film, graphite, or the like.

The first protective window 31 may protect the first display 361. The first protective window 31 may, for example, include reinforced glass. The bracket 32 may support the first display 361. The bracket 32 may at least partially include a metal.

The first printed circuit board 34 a and the second printed circuit board 34 b may be disposed inside the housing 310 such that at least one electronic component is mounted thereon. The flexible printed circuit board 34 c may electrically connect the first printed circuit board 34 a and the second printed circuit board 34 b.

The battery 389 may be positioned inside the housing 310. For example, the battery 389 may be positioned between the bracket 32 and the second surface.

The second display 362 may be exposed or viewable through a partial area of the second surface of the housing 310. The second display 362 may include no structure that interferes with transmission/reception of radio signals (for example, display sheet 361 b). For example, the second display 362 may include, for example, and without limitation, an organic light-emitting diode (OLED) display.

The second protective window 35 may protect the second display 362. The second protective window 35 may, for example, include reinforced glass.

The support 33 may be positioned between the first printed circuit board 34 a and the second display 362 so as to support the second display 362. The support 33 may, for example, include a metal (for example, steel use stainless (SUS)).

The short-distance wireless communication antenna 397 may be positioned (or disposed) at the lower end of the second display 362. For example, the short-distance wireless communication antenna 397 may be disposed between the support 33 and the second display 362. The short-distance wireless communication antenna 397 may not transmit/receive radio signals through the first surface of the electronic device, due to the metallic support 33, and can transmit/receive radio signals through the second surface of the electronic device.

The electronic device according to an embodiment may include a wireless charging antenna (not illustrated) instead of the short-distance wireless communication antenna 397. The electronic device may include both the short-distance wireless communication antenna 397 and the wireless charging antenna on the lower end of the second display 362. Although not illustrated in FIG. 3A, the electronic device may include, for example, and without limitation, a receiver, a camera module, a sensor module, and the like on the second surface.

FIG. 3B is a sectional view illustrating an example method for mounting a short-distance wireless communication antenna of an electronic device according to another embodiment.

Referring to FIG. 3B, the electronic device according to another embodiment (for example, electronic device 101 or electronic devices 201, 202, and 203) may have a short-distance wireless communication antenna 397 mounted between a battery 389 and a second display 362. For example, a battery 389 may be disposed on the lower end of a bracket 32 supporting a first display 361, a support 33 may be disposed in a partial area of the lower end of the battery 389 so as to support the second display 362, and a short-distance wireless communication antenna 397 may be disposed between the support portion 33 and the second display 362. The short-distance wireless communication antenna 397 cannot transmit/receive radio signals through the first direction (first surface) due to the metallic bracket 32 and/or the first display 361. However, since the second display 362 includes no metal housing, the short-distance wireless communication antenna 397 can transmit/receive radio signals through the second direction (second surface).

The electronic device may further include a camera module 380 and a receiver 355 in a partial area of the second surface.

FIG. 3C is a sectional view illustrating an example method for mounting a short-distance wireless communication antenna of an electronic device according to another embodiment.

Referring to FIG. 3C, the electronic device according to another embodiment (for example, electronic device 101 or electronic devices 201, 202, and 203) may have a short-distance wireless communication antenna 397 disposed between a housing 310 and a second protective window 35. For example, if the second surface having no second display 362, no fingerprint sensor 376, no camera module 380, and no receiver 355 mounted thereon has a partial area large enough to mount a short-distance wireless communication antenna 397, the short-distance wireless communication antenna 397 may be disposed between the housing 310 and the second protective window 35. The second display 362 may be positioned on the lower end of the battery 389 and supported by the housing 310.

In some embodiments, the first luminance sensor may be positioned on a side surface of the electronic device.

The processor according to an embodiment may determine representative luminance in operation 605. For example, the processor may compare first luminance measured through the first luminance sensor and second luminance measured through the second luminance sensor, and may determine the higher value as the representative luminance. This is because one of the first and second luminance sensors may be covered by a hand or an external object. According to another example, the processor may determine the average value of the first luminance and the second luminance as the representative luminance. According to another example, the processor may determine the first luminance as the representative luminance when the first display faces upward, and may determine the second luminance as the representative luminance when the second display faces upward. According to another example, the processor may assign different weights to the first luminance and the second luminance, calculate the average value thereof, and may determine the calculated average value as the representative luminance. However, it will the understood that the various manners of determining the representative luminance are not limited to the above examples.

The processor according to an embodiment may control the brightness of the first display and/or the second display based on the determined representative luminance in operation 607.

It has been assumed in the description with reference to FIG. 7 that first luminance and second luminance are measured when an event occurs, and the representative display to provide information is accordingly determined. In some embodiments, the processor may periodically measure first luminance and second luminance in a standby state, may determine the representative display to display information, and may display information through the previously determined representative display when an event occurs. However, it will be understood that measuring the first and second luminance is not limited to the above examples.

Referring to FIG. 8, the processor (for example, processor 120) of the electronic device according to an embodiment (for example, electronic device 101 or electronic devices 201, 202, and 203) may confirm whether or not measured luminance values are different in operation 801. In some embodiments, the processor may confirm whether or not the difference between the measured luminance values exceeds a designated reference value.

If it is confirmed in operation 801 that the luminance values are not different (“No” in operation 801), the processor may proceed to operation 807 (described later). If it is confirmed (“Yes”) in operation 801 that the luminance values are different, the processor may confirm in operation 803 whether an object (for example, hand, floor, or the like) is close to the display disposed on the surface having a low luminance value (for example, first surface or second surface).

If it is confirmed in operation 803 that no object is close (“No” in operation 803), the processor may proceed to operation 807 (described later). If it is confirmed (“Yes”) in operation 803 that an object is close, the processor may determine the display, to which the object is not close, as the representative display in operation 805.

The processor according to an embodiment may confirm the direction of the electronic device in operation 807. For example, the processor may confirm the direction of the electronic device using an acceleration sensor, a six-axis sensor, or the like.

The processor according to an embodiment may determine the representative display based on the direction of the electronic device in operation 809. For example, the processor may determine the overlying display, among the first display and the second display, as the representative display based on the confirmed direction of the electronic device.

After determining the representative display, the processor may return to operation 707 in FIG. 7.
